TO ALL WHOM IT MAY CONCERN:

Bc it known that we, EDRGE STORER, of New Britain, in the county ofHartford, and GEoRGnW. S'Ionnn,

A oi' Portland, in thc county of Middlesex, and vState of Connecticut,have invented, made, und applied to use a.

certain new :rnd useful improvement in Attachments for theCentre-Boards' of Vessels; and we do herebyxlecln-re the following to bei'nll, clear, und exact description of the said invention, referencebeing had tothe Aannexed dra-wing, mnkingl of this speciiication,whereini igurc 1 is :t verticul section transversely of the truulrrshoiving our improved nttuchment for the centrebonrd and i Figure is onend view of the screw-socket. l I

Vessels of vurious'sizcs and chnractcrsnre itted with centre-boards thatcan be raised or lowered-.in a. trunk that stands longitudinally of thevessel 'in the centre thereof. Thev centre-hoard is usually attached byn. pin that isdriv'ien through holes in the trunk und centre-boztrd. Inconsequence of the strain on this pin, and the frequent removalsot' thesume, e. leek is apt to occur et the said pin, and sometimesconsiderable damage is done. before it is discovered.

The nature of A'our said inveutioncousists in o. screw-socket passinginto a. hole in the Vside of the trunl:

and receiving the4 pin thntettcches thccentrc-board; by this means thecentre-pin' is sustained. so that it is not liable to bend.' The pincony be taken out with facility for' allowing the centre-board to heremoved, and u perfectly tight joint is insured, so that leakage iseileetuslly prevented.

In the drawing, a represents c portion of the trunk, fitted centrally ofthe vessel, and opening outwardly through the bottom of the vessel inany known or Vdesired manner. b is a. portion ofthe centre-boeriwhich isof suitable size, and constructed and m'oved in the usuel Way. c is ourscrew-socket, formed with a hole running into it from the inner end, forreceiving the =pin d that posses through the centre-board, and forms itsattachment und centre of motion. The socket `c is screwed into nhole ofa. size adapted to its reception passing through the trunk; and Wepreferthct the screwrportion 1 l of said socket be made slightlytapering'. A polygenel heed, 2, serves for a. wrench tobenpplicd inscrewing or unscrewing the socket, and We ernploy a. flange, 3, rroundthe outer end .of the socket, having a. V-shztped nnnulus to press intothe surface of the woedend insure s. tight joint. There may also be awasher of leather or rubber introduced between the socket and' thetruuk, or tnllow lmay be applied te the socket Where it screws into thewood. We prefer that two of these sockets be employed, one et euch endof the centre-pin d, and they Aare so shown in the drawing; This allowsthe centre-piu to be taken out from either side of the trunk, es muybemost convenient.

What We claim, and desire to secure by Letters Patent, is-

ThescreW-socket c, receiving -the centre-pin d of the centre-board, andforming a. water-tight connection with the trunk a, substantially esspecified. y

In witness whereof wehuve hereunto set our signatures this twentyitthday of October, A. D. 1866.
